, its just you create one that will extinct after a short period of time, and forgive me for saying thing, but i thing thats playing at being God and it wrong
The Fear of ruining blood lines of birds for me i agree is rubbish, at the end of the day, IF the Hybrids of two species was to survive and able to produce there own young, they would at somepoint have there own blood lines LIKE the Bengalese, The Bengalese is the most famous Hybrid, that was Silverbill X with i cant remember LOL and that survived to live and breed for hundreds of years, probably also due to the fact that they are so layed back and never been in the wild. i wonder how many people know that Bengalese (society) finches is a hybrid.

im sorry, a one off hybrid is not a species, its a mix of species. thats like saying every mongrel dog is a breed in its own right... its not
and if a sterile hybrid is produced... so what? it makes no differance.
the bengalese is NOT a hybrid, thats a very popular myth, and its not in any way desended from any species of silverbill. having said that, bengalese will readily hybridise with silverbills and produce fertile offspring, indicating they are closely related. the bengales is a domesticated strain of the sharp tailed munia, also known as the white rumped munia (lonchura striata). genetic studys have shown that these birds are the ancestor of bengalese, its only in recent times that the bengalese has had hybrid blood added into cetain strains. their voice, behaviour, courtship displays and DNA are identical and the bengalese and the sharp-tails will readily breed.
